Abstract
A method and apparatus for removing liquid from particles of compressible material includes feeding particles to two opposing press surfaces that are separated by a distance that decreases along a feeding direction wherein at least one of the press surfaces is formed of a number of parallel transfer elements and wherein each transfer element is connected to a corresponding pressing actuator. The sum of a surface area of each transfer element forms a total press surface area for one of the press surfaces. The transfer elements are reciprocated in a forward and backward motion along the conveying direction such that a total press surface area includes at any particular time a forward moving surface area that is larger than any backward moving surface area.
